From the perspective of supply and demand of water resources for cultivated land use, this paper comprehensively considered cultivated land use type, crop planting structure, crop growing period and other conditions, combined with the data from the national meteorological stations in Heilongjiang province, and explored the water demand for cultivated land use and effective water supply on the micro scale. Based on this, the spatio-temporal dynamics of land and water resources matching in different growing periods from 1990 to 2018 were analyzed. The results show that: the cultivated land structure of Heilongjiang had been changing from 1990 to 2018, and the phenomenon of changing from dryland to paddy was the most common from 2010 to 2018; the demand for water was greater in the early and middle stages of crop growth compared with the later stage. The water demand increases year by year, which is consistent with the change of paddy proportion, and the migration law of areas with high water demand is highly consistent with the phenomenon of dryland converting to paddy in the same period. From 1990 to 2018, the matching degree of land and water resources in each growth period of crops decreased first and then increased. Most high-value areas of land and water resources matching are distributed in the interface between high-value areas of effective precipitation and dryland areas. It can be seen that natural precipitation is still the main source of water for cultivated crops. In recent years, the matching degree of land and water resources in the southern part of the Sanjiang Plain decreased obviously, and the unit yield of grain declined. It is suggested to reduce the quantities of dryland-to-paddy conversion projects in this area. At the same time, the matching level of land and water resources and the unit yield of grain in the western part of the Songnen Plain increased year by year, so the dryland-to-paddy conversion project can be carried out appropriately.
